This invention relates to certain novel-improvements in extensible hay racks, andlhas.

for its principal object the provision of an improved construction of this character E which will be highly elicient in use and economical in manufacture.

Among the several objects of'` this invention is the provision of an improved construction of the character described herein which when not in vuse can be storedin'a compact space such asunder a small roof.

Other objects will appear hereinafter.

The invention consists in thenovel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings, showing the preferred forni of construction and in which:

Fig. l is a side elevational view depicting a preferred form of construction of my iinproved wagon box and hay rack;

Fig. 2 is a plan view of the Vinvention asV depicted in Fig. l, taken substantially on the line 2-2 in Fig. 1; and Y Fig. 3 is a sectional viewtaken substantially on the line 3-3 in Fig. 2. p

Referring to the drawing wherein a preerred form of construction of my invention is depicted, indicated at 10 is a front wheel bearing axle structure which may be of any approved type so as to support kthe iront wheels 11 and 12. Extended between the front axle structure 10 and a suitable rear wheel bearing axle structure 13 is an extensible reach 14 of any approved type known in the art. Carried by the rear` axle structure 13 are the rear wheels 15 and 16. Associated with the front axle structure 1,0 is a tongue 17 which may be of any' approved type. Y' The tongue structure 17 is swivelly con# nected tothe front axle structure l10 by means of the circle 18 as is well known in the art. `Carried by the front axle structure 10 is a cross piece 19 which may beof any approved type and in the present instance this portion 19 is similar to a cross piece .20 car-v ried by the rear axle structure 13. The foregoing described structurel constitutes no part of my inventionand may be of anyapproved type.

My improved hay rack construction includesL-a box-like structure generically indicated at'21.. Mounted on the box 21 are angle irons 22 and 23 which are adapted to engage the cross piece 19 when my improved device ismounted in operative position and, as is well understood in the art, these portions 22 and 23 prevent longitudinal movement of the box 21 when the box is in operative position. Angle irons or the like 24 and 25 are carried by the box 21 in position so as to cooperate with the rear cross piece 20.

The side walls of my improved box 21 are defined by similarfrontand rearpairs of elongated channel irons 26 and 27. The front pair ofirons 26 and 27 are secured together by end plates 28 and suitable securing elements such as 30 and 31. The rear pair of irons 26`and 27 are secured together by plates 29 and suitable connecting elements 31. As best shown in Fig. 3, these channel irons 26 and 27 are substantially rectangular in cross section to provide inwardlyextending flanges 26 and 27 and are spaced apartat the middle of thel box 21V as indicated at 90. Provided at spaced apart intervalsvin the longitudinal extentof the channel irons 26 and 27 are plates 32 and 33 which are secured to the channel irons 26 and 27 lby means of suitable `connecting elements 34.V `Extending longitudinally between the channel irons 26 and 27 are boards 44 which are extensible with e respect to the channelirons 26 and 27. The platesv 32 and 33 are connected to the boards 44 by means of bolt and nut structures 35; Adjacent 'the middlejof the box `21 and yat theiiiner ends of the irons 26 and 27 I provide plates 36 andv 37 which are rigidly sel Vcured to the channel irons 26 and 27 by means lPA'rfE-NT OFFICE: jg

at the rear of the box 21 and this iron45 extends bet-ween the plates 29.

The bottom ofthe box 21 is provided by planks 47 which at the rear ends thereof are mounted upon and; secured to the angle iron by means of securing elements 46, while the front end portions of the planks 47 rest upon and are secured tothe angle iron 42 by means of securing elements 43. Y l

It is manifest, therefore, that the box 21 may be extended by removing the bolt and nut structures 35, 40, 41 and 36 from each of the side walls and Athen removing the bolts 43 and 46 from the floor planks 47. It is apparent that I may thus provide planks 47 of-various lengths corresponding to the'vae rious lengths to which the box 21 may be extended and to facilitate securing the bolts and. nut structures 35,40 and 41 in the several positions to which the vbox 21 may be extended I provide suitable openings in the boards 28. f

Mounted on the flange portions 26 of the rearwardly disposed pairs of channel irons 26 and at the rearthereof are standards 47 which include foot portions 27 which are attached to the liange portions 26 by means of suitable securing elements 48. Disposed forwardly of the standards 47 are similar standards491which include foot portions49 which are attached toithe flange' portions 26 by means of securing elements V50. Disposed be-v tween the standards 47. and49 and extending transversely ofthe box 21 is an angle iron 51 which includes a flange portion 51 and this angle iron 51 is secured to the standards 47 and 49 by means of securing elements 52.

Spaced forwardly of the lstandards 47 and 49 on the rearward-ly disposed pair of irons 2 6Y and 27 are similar standards 53 andl 54 which are mounted on the flange portions in af manner similar to that described for the standards 47 and 49 and these standards support a transversely extending angle iron which includes a flange portion. 55.

Mounted on the flange' portions 51 andl 551 and/extending parallel to the side walls of. the; box 21, but spaced apart therefrom, as shown in Figs. 2 and 3, are boards 56; These boards 56 are secured to the flange portions 51 and 55 by means Iof suitable bolt and nut structures 58 and 59'.V

Standards 60 are provided at the frontend ofthe box 21 Lon the forward. pair of irons 26 and 27l and these standards include foot portions 60 which are attached to the Vflanges 26. by meansv of securing elements 61. Adjacent the standards 60' are standards62 which includefoot portions 62" that are se-V cured to the flange portions Y26 by means of suitable securing elements and these' standard'sj 60 and 62 support a transversely extending channel iron 63 which is attached to the standards 60 and62 by means of suitable securin-glelements. Standards 65 and 66 sims ilar to the standards 60 and 62 are provided on the flange portions 26' of the forward pair of irons 26 and 27 and these standards support an angle iron 67 which is similar to the angle iron 63 and includes a flange portion 67. Extending between the flange portions 67 at opposite sides ofthe box 21j a`re boards 68 which are extended parallel tothe boards 56 but spaced below the boards 56 as shown in Figs. 1 and 3. The boards 68 are connected to thel flange portions 6'7n and 63 by means of bolt and nut structures 69 and 70.

` It maybe seen, therefore, by referring to Fig.v 1, that when the box 21 is extended in the manner described hereinbefore the boards 68: will move sli'dably under the boards 56' so that my improved hay rack may be extended to any desired length'.

My improved hay rack inclu'desa ladder structure generically indicated' at 71. VThe ladder 71 comprises spaced apart legs 72 and 73 toy which are secu-red in any approved manner plates 74 and 7 5 and, as showrr in F ig. 2, these plates 74 and 75 are mounted for swinging movement on a shaft 76 which carries spacing collars 77 and 78. 'l-he endV por-v tions r6i/.of thev shaft 76 are mounted in any approved manner in suitable openings provided therefor ilrthe plates 30. Extending between the legs- 72 and 73 of thel ladder 71 are the cross pieces 79. i

t is apparent, tlierefore',fthat the ladder 71 may be moved forwardly into operative position, as shown in Figs. 1 and' 2', andA in this position the legs 72 and73 of the ladder rest against the angle iron 42 while wheny not in use the ladder 71 may be disposed on the floor ofthe box 21.

At the rear ofi my improved hay rack provide standards 80 and 81', for purposes well understood in the art.y The standards 80 and 81 are provided byl arms 82-and-'8-3 which are secured respectii'iely top'lates 84 and' 85v by means of. securing elements 86 and 87. The platesV 86 and 87 inclu'de similar offset portions 84 and 85 and these' offset portions are' mounted for swinging movement in the plates 29 bymean's of bolts 88 and 89'. The standards 86 and 81A when in operative position rest on the Hoor planks 47.

From the foregoing description of my in venti'on it is manifest that I' have provided an improved hay rack coiistru'cti'o'n which may ibe' extended to various lengths and which', when not in= use,y may be stored in a compact space. It is likewise apparent from 'the foregoing description of invention that while being simple and economical! in construction my invention is high-ly convenient and: efficient inl use.
